wifi/BT/RF motion sensor to activate recirculation pump for

by Father_of_Ash on Wed Jan 30, 2019 9:33 pm

Hello All.
I recently discovered this site in the process of researching how I can wireless activate a re-circulation pump on my water heater and I found the M4 RF transmitter relay which I thought was nice. but then realized a motion sensor would be the perfect solution.
I'm hoping someone can help me find the most efficient configuration for a motion sensor to wireless/Bluetooth/Radio-frequency activate a momentary relay connected to the water heater. the water heater does have an option for a wired momentary push button.

Any-ones help would be much appreciated.

Let's start out with an explanation of what sequence of events and triggers you want to achieve.

Hi, thank you for the reply.
I walk into the bathroom and some type of motion or proximity sensor activates and sends signal to a momentary relay at the heater. I would also like to add 2 wireless push buttons to activate the relay the same way, unless it will over complicate this system.

please let me know if there are any other details you need.

How far from the bathroom to the heater button and where are the two remote switches to be located in relation to this?

Bathrooms are on second floor max 30ft. Heater is in basement.
wireless push buttons would be relatively close. one about 10-15ft. away. the other on 1st floor roughly 15ft. away.

Hello
Would it be possible to wire an IR beam sensor into one of your single push button 315mhz RF remotes? Once the beam is broken it will act as if the button was pushed? part #s 1392 & 2167. And use the Simple RF M4 Receiver part# 1096.

Would it be as simple as wiring the signal and negative wires to the remote push button and feed it 5v?

Thank you.

A transistor may be needed to create the short but it is doable.

Thank you for the response.
I guess I didn't read the description the first time... The IR beam is only good for 10"-20" and requires reflector.
I think the PIR sensor ID#189 will work much better. would i need a 10k resistor for this as well? and do you offer tiny power supplies for this? or will it run off battery for a decent amount of time?
